Tibilov represented Ukraine at the 2008 Summer Olympics in Beijing, where he competed for the men's 96 kg class. He received a bye for the preliminary round of sixteen match, before losing out to Russia's Shirvani Muradov, with a three-set technical score (1–0, 0–1, 0–1), and a classification point score of 1–3.[3] Because his opponent advanced further into the final match, Tibilov offered another shot for the bronze medal by defeating Turkey's Hakan Koç in the repechage round. He progressed to the bronze medal match, but narrowly lost the medal to Azerbaijan's Khetag Gazyumov, who was able to score seven points in two straight periods, leaving Tibilov without a single point.[4]
